METALLIC HAIVlB-FASTENER.

SPECIFICATION forming part of Letters Patent No. 341,748, dated May 11,18116.

Application filed February 25. 1886. Serial No. 1932140. (No model.)

To (LZZ whom, it may concern:

Be it known that I, ADELBERTL. GIJER, of Plymouth, in the county of\Vayne and State of Michigan, have invented new and useful Improvementsin Metallic Hame-Straps; and I do hereby that the following is a full,clear, and exact description thereof, reference being had to theaccompanying d rawi ngs, which form a part of this specification.

This invention relates to certain new and novel improvements inhame-straps; and the invention consists in the peculiar construction,arrangement, and combination of the parts, all as more fully hereinafterset forth.

Figure 1 isaside elevation. Fig. 2 is a perspective view of the twoparts of my device detached from each other. Fig. 3 isa centrallongitudinal section of Fig. 1. Fig. 4. isa crosssection of Fig. 1.

In the accompanying drawings, which form a part of this specification, Arepresents one portion of my improved hame-strap, preferably made ofmalleable iron,and provided with a hook, a, by means of which it isattached to the hame. The body of this iron A is bifurbars, b, throughwhich pins 0 are rigidly secured at or about equal distances apart.

B represents the other or male portion of my improved device, which ispreferably provided with a hook, d, upon one end for securing it to itsrespective hame. The opposite end of this portion B is slightly hooked,as shown, and is bifurcated, having pivotally secured in suchbifurcation a lever, D, the short arm of which terminates in ahook-head, I], with a flattened surface, 6.

F is a spring, which is secured at one end to the portion B, its freeend overlapping the head E of the leverD.

In practice, the two parts of my device being secured to the hames, whenit is desired to 5 close the hames upon the collar, the lever O isinserted behind the proper pin, 0, of the part A, and is then drawnupwardly into the position shown in Figs. 1 and 3, the end of the springbearing down upon the flattened surface e of the head of the lever. Itwill be noticed that in this position the strain caused by the expandingof the collar and hames in drawing is brought upon the hook of the headE, which is above the fulcrum of the lever, and hence the greater thestrain the more tightly the lever is held in its closed position.

The mere function of the spring is, when the hames are not drawn tightlytogether, to prevent the lever D from dropping down and allowing theparts to disengage. Therefore it will be seen that if care is taken toproperly tighten the hames, so that the expansion of the collar will besuiiicient to keep the parts in engagement, this spring F may beomit-ted without departing from the spirit of my invention.

\Vhat I claim as my invention is 1. In a metallic hame strap, thecombination of the parts A, B, and D, the latter being provided with ahook-head, E, with the spring F, all constructed, arranged, and.operating substantially in the manner and for the purposes specified.

2. In a metallic hanie strap, the combination, with the part A, providedwith a plurality of pins, 0, of the part B, lever D, pivoted thereto,the short arm of said lever terminating in a hook-head, E, havingflattened surface 6, and the spring F, secured to said partB and bearingon said flattened surface, substantially as and for the purposespecified.
